Definitions
- the invention relates to a connector for catheters with a flow channel connecting the catheter and an inner cone connection and a valve.
- Catheters are used in medicine for the supply and removal of liquids in or from the vascular system of the human body.
- this catheter to securely attach this catheter to other devices such as e.g.
- the end of the catheter facing away from the patient is firmly connected to a connector.
- the free rear end of the connector usually has an inner cone for receiving a corresponding male connector cone of the device to be connected.
- the connection is made using a standardized so-called Luer lock connection.
- Luer lock connection In order to prevent blood from escaping from the connector of the catheter or from entering the vascular system of the body when a connector is removed or replaced, connectors with a valve device have proven effective.
- a connector for catheters with valve device is known for example from DE-C1-3100442.
- a shut-off valve disk made of elastomeric material with at least one central slot is held in the passage channel of the connecting piece disclosed there.
- the object of the present invention is to provide a connector for catheters with a flow channel connecting the catheter and an inner cone connector to provide a valve that is as simple as possible and is inexpensive to manufacture.
- valve by means of a cup-shaped valve body made of elastomeric material which is longitudinally displaceable in the passage, the rear open end of which has an inner cone and the bottom of which has at least one central slot, and a truncated cone centrally directed to its bottom with a central passage opening is formed, and that the bottom is at least partially penetrated by the truncated cone in the advanced position of the cup-shaped body.
- the bottom of the cup-shaped valve body has two mutually perpendicular slots.
- the inner cone of the cup-shaped valve body For the valve function of the connecting piece, it is favorable to give the inner cone of the cup-shaped valve body a greater steepness than the standardized male cone of the device to be connected. Due to this greater conicity of the inner cone of the cup-shaped valve body, it adheres better to the immersing male cone of the device to be connected. During deconnection, the valve body is taken backwards by the male cone of the device to be connected due to this liability and is only stripped off by this when the rear end of the valve body has a rear boundary, e.g. an annular shoulder in the passage channel.
- valve device simplifies the manufacture of fittings with valves without any loss of functionality. Compared to the prior art, it is no longer necessary to install a valve disk in the connector in a fixed position.
- the connector itself can be made, for example, of two parts, the first part being connected to the catheter and the second part containing the inner cone connection. Before connecting the two parts together the cup-shaped valve body representing the valve is inserted into the passage.
- the two parts can be permanently connected, for example by gluing or welding.
- connection pieces according to the invention are known to the person skilled in the art.
- a silicone polymer is particularly suitable for the valve body.
- a connector dismantled into its parts is shown.
- the front section 9 is connected to the catheter tube 8.
- This front section 9 narrows at its rear end to form a truncated cone 7.
- the cup-shaped valve body 3 made of elastomeric material ends rearward in an inner cone 4, which starts from a ring shoulder 15 directed towards the rear.
- the bottom 5 of the valve body 3 has a central slot 6 and on the outside a central conical depression 12.
- the rear section 10 of the connecting piece is designed as an inner cone connection 11 with a ring shoulder 13 directed forward.
- Fig. 2 shows a connector 1 in assembled ready-to-use form.
- Valve body 3 lies with its opening to the rear in the passage channel 2 of the rear section 10 and lies against the annular shoulder 13.
- the truncated cone 7 of the front section 9 lies against the bottom 5 of the valve body 3 and presses it against the annular shoulder 13 of the rear section 10.
- the passage 2 of the connection piece 1 is thus closed.
- Fig. 3 shows a connector 1 with a rear-mounted connector cone 14.
- the front end of the connector cone 14 fits into the inner cone 4 of the valve body and is supported against the rearward-facing annular shoulder 15 of the valve body 3.
- the Valve body 3 With the insertion of the connector cone 14, the Valve body 3 shifted forward and its bottom 5 pressed against the truncated cone 7 of the front section 9.
- slot 6 opens in the bottom 5 of the valve body 3 and releases the flow through the passage channel 2.
- the connecting cone 14 is removed, the slot 6 closes due to the restoring force of the elastomeric material of the valve body 3 and the rear end of the valve body is pressed again sealingly against the annular shoulder 13 of the rear section 10.
Abstract
Description
- Die Erfindung betrifft ein Anschlußstück für Katheter mit einem den Katheter und einen Innenkonusanschluß verbindenden Durchflußkanal und einem Ventil.
- Katheter finden in der Medizin für die Zuführung und die Entnahme von Flüssigkeiten in oder aus dem Gefäßsystem des menschlichen Körpers Anwendung. Um diese Katheter sicher mit anderen Vorrichtungen, wie z.B. medizinischen Spritzen oder Infusionsschläuchen verbinden zu können, ist das patientenabgewandte Ende des Katheters fest mit einem Anschlußstück verbunden. Das freie hintere Ende des Anschlußstücks weist in der Regel einen Innenkonus zur Aufnahme eines entsprechenden männlichen Anschlußkonus der anzuschließenden Vorrichtung auf. Beispielsweise erfolgt die Konnektierung durch einen genormten sog. Luer-Lock-Anschluß. Um zu verhindern, daß beim Abnehmen oder Wechseln eines Anschlusses Blut aus dem Anschlußstück des Katheters austritt oder Luft in das Gefäßsystem des Körpers eintritt, haben sich Anschlußstücke mit Ventileinrichtung bewährt.
- Ein Anschlußstück für Katheter mit Ventileinrichtung ist beispielsweise aus DE-C1-3100442 bekannt. Im Durchtrittskanal des dort offenbarten Anschlußstückes ist eine absperrende Ventilscheibe aus elastomerem Material mit mindestens einem zentralen Schlitz gehaltert. Beim Aufsetzen eines Anschlußkonus auf den Innenkonus des Anschlußstücks wird ein längsverschieblicher rohrförmiger Körper gegen die Ventilscheibe gedrückt, so daß der Schlitz geöffnet wird. Beim Entfernen des Anschlußkonus drückt die elastisch verformbare Scheibe den rohrförmigen Körper zurück, wobei sich der Schlitz dichtend schließt.
- Aufgabe der vorliegenden Erfindung ist es, ein Anschlußstück für Katheter mit einem den Katheter und einen Innenkonusanschluß verbindenden Durchflußkanal und einem Ventil zur Verfügung zu stellen, das möglichst einfach gebaut ist und kostengünstig herzustellen ist.
- Gelöst wird diese Aufgabe dadurch, daß das Ventil durch einen im Durchtrittskanal längs begrenzt verschieblichen, becherartig geformten Ventilkörper aus elastomerem Material, dessen rückwärtiges offenes Ende einen Innenkonus und dessen Boden mindestens einen zentralen Schlitz aufweist, und einen zentral auf seinen Boden gerichteten Kegelstumpf mit zentraler Durchtrittsöffnung gebildet wird, und daß der Boden in der vorgeschobenen Stellung des becherartig geformten Körpers vom Kegelstumpf mindestens teilweise durchsetzt wird.
- Eine vorteilhafte Ausführung erhält man dadurch, daß mindestens eine Seite des Bodens des becherartig geformten Ventilkörpers eine zentrale kegelförmige Vertiefung aufweist.
- Bei einer weiteren vorteilhaften Ausführung ist vorgesehen, daß der Boden des becherartig geformten Ventilkörpers zwei zueinander senkrecht stehende Schlitze aufweist.
- Für die Ventilfunktion des Anschlußstücks ist es günstig, dem Innenkonus des becherartig geformten Ventilkörpers eine größere Steilheit zu verleihen als sie der genormte männliche Konus des anzuschließenden Geräts aufweist. Durch diese größere Konizität des Innenkonus des becherartig geformten Ventilkörpers haftet dieser besser auf dem eintauchenden männlichen Konus des anzuschließenden Geräts. Bei der Dekonnektion wird der Ventilkörper aufgrund dieser Haftung vom männlichen Konus des anzuschließenden Geräts nach rückwärts mitgenommen und erst von diesem abgestreift, wenn das rückwärtige Ende des Ventilkörpers eine hintere Begrenzung, z.B. eine Ringschulter im Durchtrittkanal, erreicht.
- Durch die erfindungsgemäße Gestaltung der Ventileinrichtung vereinfacht sich die Herstellung von Anschlußstücken mit Ventilen ohne daß es bezüglich der Funktionalität zu Einbußen kommt. Im Vergleich zum Stand der Technik ist es nicht mehr notwendig, eine Ventilscheibe ortsfest in das Anschlußstück einzubauen.
- Das Anschlußstück selbst kann beispielsweise aus zwei Teilen gefertigt sein, wobei das erste Teil mit dem Katheter verbunden ist und das zweite Teil den Innenkonusanschluß enthält. Vor dem Verbinden der beiden Teile miteinander wird der das Ventil darstellende becherartig geformte Ventilkörper in den Durchtrittskanal eingelegt. Die beiden Teile können beispielsweise durch Kleben oder Schweissen unlösbar verbunden werden.
- Die für erfindungsgegenständliche Anschlußstücke in Frage kommenden Werkstoffe und Produktionsverfahren sind dem Fachmann bekannt. Für den Ventilkörper eignet sich insbesondere ein Silikonpolymeres.
- Nachstehend wird ein Ausführungsbeispiel der Erfindung anhand der Fig. 1 bis 3 näher erläutert.
- Fig. 1 zeigt einen Längsschnitt durch ein auseinandergenommenes Anschlußstück.
- Fig. 2 zeigt einen Längsschnitt durch ein Anschlußstück mit geschlossenem Ventil.
- Fig. 3 zeigt einen Längsschnitt durch ein Anschlußstück mit aufgesetztem Anschlußkonus.
- In Fig. 1 ist ein in seine Teile zerlegtes Anschlußstück dargestellt. Das vordere Teilstück 9 ist mit dem Katheterschlauch 8 verbunden. Dieses vordere Teilstück 9 verengt sich an seinem hinteren Ende zu einem Kegelstumpf 7. Der becherförmige Ventilkörper 3 aus elastomerem Material endet nach rückwärts in einem Innenkonus 4, der von einer nach rückwärts gerichteten Ringschulter 15 ausgeht. Der Boden 5 des Ventilkörpers 3 weist einen zentralen Schlitz 6 und außen eine zentrale kegelförmige Vertiefung 12 auf. Das hintere Teilstück 10 des Anschlußstücks ist als Innenkonusanschluß 11 mit nach vorwärts gerichteter Ringschulter 13 gestaltet.
- Fig. 2 stellt ein Anschlußstück 1 in zusammengebauter gebrauchsfertiger Form dar. Ventilkörper 3 liegt mit seiner Öffnung nach rückwärts im Durchtrittskanal 2 des hinteren Teilstücks 10 und liegt dabei an der Ringschulter 13 an. Der Kegelstumpf 7 des vorderen Teilstücks 9 liegt am Boden 5 des Ventilkörpers 3 an und drückt diesen gegen die Ringschulter 13 des hinteren Teilstücks 10. Der Durchtrittskanal 2 des Anschlußstücks 1 ist damit verschlossen.
- Fig. 3 zeigt ein Anschlußstück 1 mit einem von rückwärts aufgesetzten Anschlußkonus 14. Das vordere Ende des Anschlußkonus 14 paßt in den Innenkonus 4 des Ventilkörpers und stützt sich gegen die nach rückwärts gerichtete Ringschulter 15 des Ventilkörpers 3. Mit dem Einschieben des Anschlußkonus 14 wird der Ventilkörper 3 nach vorwärts verschoben und dessen Boden 5 gegen den nach hinten ragenden Kegelstumpf 7 des vorderen Teilstücks 9 gedrückt. Hierbei öffnet sich Schlitz 6 im Boden 5 des Ventilkörpers 3 und gibt den Durchfluß durch Durchtrittskanal 2 frei. Beim Entfernen des Anschlußkonus 14 schließt sich Schlitz 6 durch die Rückstellkraft des elastomeren Materials des Ventilkörpers 3 und das hintere Ende des Ventilkörpers wird wieder dichtend gegen die Ringschulter 13 des hinteren Teilstücks 10 gedrückt.
